5 / 18 page CDCVF2509A www.ti.com SCAS765E – APRIL 2004 – REVISED FEBRUARY 2010 RECOMMENDED OPERATING CONDITIONS (1) MIN MAX UNIT VCC, AVCC Supply voltage 3 3.6 V VIH High-level input voltage 2 V VIL Low-level input voltage 0.8 V VI Input voltage 0 VCC V IOH High-level output current –12 mA IOL Low-level output current 12 mA TA Operating free-air temperature 0 85 °C (1) Unused inputs must be held high or low to prevent them from floating. TIMING REQUIREMENTS over recommended ranges of supply voltage and operating free-air temperature MIN MAX UNIT fclk Clock frequency 20 175 MHz Input clock duty cycle 40% 60% Stabilization time(1) 1 ms (1) The time required for the integrated PLL circuit to obtain phase lock of its feedback signal to its reference signal. For phase lock to be obtained, a fixed-frequency, fixed-phase reference signal must be present at CLK. Until phase lock is obtained, the specifications for propagation delay, skew and jitter parameters given in the switching characteristics table are not applicable. This parameter does not apply for input modulation under SSC application. ELECTRICAL CHARACTERISTICS over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS VCC, AVCC MIN TYP(1) MAX UNIT VIK Input clamp voltage II = -18 mA 3 V –1.2 V IOH = -100 µA MIN to MAX VCC–0.2 VOH High-level output voltage IOH = -12 mA 3 V 2.1 V IOH = -6 mA 3 V 2.4 IOL = 100 µA MIN to MAX 0.2 VOL Low-level output voltage IOL = 12 mA 3 V 0.8 V IOL = 6 mA 3 V 0.55 VO= 1 V 3 V –28 IOH High-level output current VO = 1.65 V 3.3 V –36 mA VO = 3.135 V 3.6 V -8 VO= 1.95 V 3 V 30 IOL Low-level output current VO = 1.65 V 3.3 V 40 mA VO = 0.4 V 3.6 V 10 II Input current VI = VCC or GND 3.6 V ±5 µA VI = VCC or GND, IO = 0, ICC (2) Supply current (static, output not switching) 3.6 V, 0 V 40 µA Outputs: low or high One input at VCC - 0.6 V, ΔICC Change in supply current 3.3 V to 3.6 V 500 µA Other inputs at VCC or GND Ci Input capacitance VI = VCC or GND 3.3 V 2.5 pF Co Output capacitance VO = VCC or GND 3.3 V 2.8 pF (1) For conditions shown as MIN or MAX, use the appropriate value specified under the recommended operating conditions section.
